Volume of Reads and writes to Teradata Database.

Hi ,

I have a requirement to know the volume of Reads and Writes that are happening on Teradata database. Is there a way to find out the volume of Reads and writes happening on per day basis? I happened to find some Resusage tables but the RSS parameters are not enabled on our system. Is there a way to find out this information apart from getting the info from Resusage Tables?
